Description
Technical field
The present invention relates to the internal-combustion engine according to claim 1 preamble.
Background technique
This internal-combustion engine is generally known and by running to the mode of firing chamber delivery air-fuel mixture during aspirating stroke.In order to produce air-fuel mixture, the fuel of prearranging quatity to be ejected in suction tude and to be atomized by injection valve, and this suction tude is connected with firing chamber by suction port.At this, the closure be arranged in this suction tude determines to suck great amount of fresh air to direction, firing chamber.Along with opening of closure causes pressure to raise in suction tude, thus, the vaporization tendency of the fuel sprayed into reduces.With to be such as ejected into together with the fuel on air inlet tube wall by injection valve, fuel also accumulates in when closure is opened on air inlet tube wall due to the vaporization tendency reduced.Pressure drop in the situation lower inlet duct of closed throttle, vaporization tendency rises and the fuel accumulated on wall evaporates in suction tude, and thus, air-fuel mixture thickens.In both of these case, delivery to the fuel quantity of firing chamber in other words natural fuel amount and predetermined set fuel amount nominal fuel amount is different in other words.
Therefore generally known, coordinate the predetermined set fuel amount that is ejected in suction tude like this: the fuel loss that such as caused by the deposition of fuel on wall or gather or additional amount are compensated when load variations.This way is called as transition and compensates and be such as illustrated in document DE102007005381A1.Be necessary that in the transition compensation range of economy and environmental protection, to know on the one hand and runnability at that time be should be much for the fuel quantity change needed for compensating, want the next fuel quantity predetermined according to Operational Limits, the correction of such as suction press of this knowledge of reason on the other hand.At this, know more accurate for transition compensates necessary fuel change amount, the adaptation that transition compensates just can more accurately be carried out.Do not have if transition compensates or carry out mistakenly, then depositing the danger that air-fuel mixture is in a combustion chamber thinning or thicken.Then interruption in power can be there is in these conditions until burning cutoff.On the other hand, be defined as transition as far as possible exactly to compensate necessary fuel quantity and make internal-combustion engine can low exhaust and stably running.
In order to determine that compensation rate can take into account the characteristic of the wall film in tracheae.Gather the fuel quantity that deposits in other words thus the characteristic of wall film especially its thickness and a lot of parameter correlations, such as intake manifold temperature, suction tude pressure and rotating speed.Therefore meet target it is possible to according to these parameters especially for different runnability identify wall film characteristic and by the understanding of this coherence is come at different conditions adaptive transition compensate.Usually the fuel quantity sprayed is controlled and the transition compensation needed respectively in this consideration, by control unit or by controller especially when load changing according to runnability at this.
Know if disposable for each internal-combustion engine other, the compensating the coherence of necessary change and different parameters, especially suction press for transition and compensate for the transition of often kind of fortune situation adaptation of the fuel that will spray, then can not get rid of, change along with the time for transition compensates the change of necessary fuel quantity.In fact more will be understood that, the characteristic of wall film and thus for transition compensate necessary fuel change such as due to the dirt of suction tude or analog along with the time changes.Require again adaptive transition to compensate, to ensure that internal-combustion engine runs to low emission as far as possible to the compensation of this change.With the adaptive transition of the repetition of the method for prior art compensate not only cost high but also consuming time for a long time and be related to high expense.
Summary of the invention
The inventive method compensated according to the transition for adaptive internal-combustion engine of main claim it is possible to cost rationally and do not infer the deviation with the fuel quantity arranged for firing chamber with not needing large additional consumption relative to the advantage that prior art has.
According to the present invention's regulation, during the first method step, stop fuel to lead in the suction tude (that is the first suction tude) of firing chamber to one spray.Simultaneously during this first method step by the second suction tude or by other suction tude multiple to firing chamber delivery alternative fuel amount, this alternative fuel amount is equivalent to the fuel quantity be injected in normal operation in two or all suction tude.
The carburretion gathered on the first air inlet tube wall during this first method step, makes the air-fuel mixture imported in firing chamber thicken.
The air-fuel mixture occurred during the first method step thicken can by the change of λ value, that is by λ value change determine.At this, in the outlet of multiple firing chambers that are that be preferably placed in described firing chamber or that exist in internal-combustion engine or the λ probe be arranged in exhaust pipeline section know λ value, the residue oxygen content in the waste gas of being discharged by firing chamber quantizes by this λ value.Especially, during the first method step, can be observed rich oil degenerate (Fettausflug), namely λ value reduces also with and then raising.
In the second method step, the first test fuel amount to be ejected in the first suction tude by the first injection valve and the second test fuel amount is sprayed in the second suction tude by the second injection valve.At this, the first and second test fuel amounts and be equivalent to normal operating predetermined quantity of fuel or described alternative fuel amount.This causes, in the first suction tude on wall accumulate fuel and delivery is thinning to the air-fuel mixture in firing chamber.During the second method step, λ value change presents with the formation of oil-poor degeneration (Magerausflug), and namely first λ value raises and and reduce.
Rich oil is degenerated and/or the size of oil-poor degeneration and duration are the yardsticks of natural fuel amount in firing chamber and the quantity difference between nominal fuel amount.Therefore the λ value change will observed for runnability at that time according to the present invention is used for adaptive transition and compensates.At this, according to the present invention advantageously, use the λ probe usually existed in internal-combustion engine, because the sensitive detection parts causing surcharge using other can be abandoned like this, such as or the sensitive detection parts of wall membrane property.In addition method according to the present invention provides such advantage: not only consider that caused by fuel gathering or depositing on the wall of suction tude with deviation that is nominal fuel amount, and considers the deviation that caused by other potential cause.
In the preferred embodiment of the present invention, by the first and second fuel quantities and/or in the second method step, the first and second test fuel amounts are ejected in suction tude in the same manner under normal operation.At this advantageously, injection valve can be that structure is identical, can avoid the fringe cost caused owing to producing another kind of type injection valve thus.
If repeat the method for different runnability, then obtain about natural fuel amount and nominal fuel amount to likely the deviation that runnability is relevant general view and adaptive transition can be carried out for often kind of runnability and compensate.Specify in the preferred embodiment of the present invention, formulate characterisitic family, the transition be adapted compensates corresponding with to runnability at that time by it.Especially specify, by control program, such as by DOE program pin, often kind of runnability is revised to the fuel quantity that will spray.The special advantage of this mode of execution is, runs to the special low emission of internal-combustion engine and ensure the stable operation of internal-combustion engine at this under different runnability.
In another preferred implementation of the present invention, when the first method step starts and/or when the second method step starts, know that λ value changes.If only sense λ value change when the second method step starts when the first method step starts or only, then advantageously reduce the evaluation cost of λ probe.If not only determined that λ value changed when the first method step starts but also when the second method step starts, then measuring accuracy can be improved.
According to another preferred implementation regulation of the present invention, working, run duration performs the first and second method steps, namely knows with the deviation of the nominal fuel amount arranged for firing chamber and it is used for adaptive transition to compensate.Work is run and is interpreted as not only for the operation of test purpose.At this particularly advantageously, abandon testing in the preparatory stage with expending time in all runnability of imagining and then formulate characteristic family.Replace regulation, once internal-combustion engine runs under the runnability be not considered so far, then existing indicatrix group is before compensated according to the transition be adapted and expand or revise, know the characteristic family of natural fuel amount and nominal fuel amount in this way step by step, i.e. wall membrane property.
In another preferred implementation of the present invention, again compensate for the adaptive transition of different runnability after scheduled time.If the coherence of wall membrane property or change for runnability with the deviation of the fuel quantity arranged for firing chamber of internal-combustion engine, then compensate with the new transition be adapted and substitute until the transition that this time point uses compensates.
In another preferred implementation of the present invention, once determine that the discharge of internal-combustion engine after combustion process changes, especially be deteriorated, then internal-combustion engine is independently transformed into test phase (that is performing the first and second method steps) in next back to back as far as possible opportunity.Be deteriorated such as can by normal operation with the deviation of the rating value of λ value or also show by the variation of waste gas value.In test phase, under different possible runnability, know wall membrane property according to one of preceding method and then adaptive transition compensation again.
